SPECIFICATION forming part of Letters Patent No. 325,363, dated September 1, 1885.

Application filed December 26. 1884. (No model.)

To all whom, it may concern:

Be it known that we, "VERNON RoYLE and JOHN RoYLE, Jr., of the city of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Machines for Making Tubing and Cord and for Covering Telegraph and other Wires, of which the following is a specification, reference being had to the accompanying drawingslorming part of this specification.

This invention relates more particularly to machines for making tubing of india-rubber,

gntta-percha, or other materials of a plastic 'einbodying our invention are generally atrunk or cylinder to which the plastic mate rial is supplied, a screw fitted to the said trunk or cylinder for forcing the plastic material through and from the said trunk or cylinder with the requisite pressure, and a die in the head of the said trunk or cylinder through which the material is forced, and which gives form to the exterior of the tubing, cord, or wire-covering to be produced. A core also is employed to give form to the interior of the tube in a machine for making tubing and to steady and center the wire in a machine for covering wire, but such core being omitted in a machine for making cord.

There is also a delivery-apron for receiving the formed product of the .die. Some parts of our invention might, however, be applicable to machines in which some other means common to machinery for making tubinga.

' ram, for instance-is used for forcing the plustic material through the die.

Our invention consists in certain novel means of heating and regulating the heat of the body, trunk, or cylinder, and the head thereof, which contains the die and forming devices, whereby the several parts of the machine are brought to a proper temperature and the plastic material under operationis upper part of the machine viewed from the kept properly tempered for obtaining the best results.

Our invention also consists in certain provision for the adjustment of the core, when one is used in the machine, whereby its concentricity to the die is assured.

It also consists in certain means of receiv ing the end-th rust of the pressure-screw, and

of adjusting the said screw in its proper relation to the die and core of the machine.

It also consists in certain means of driving the delivery-apron, whereby provision is atforded for varying and controlling the speed thereof that it may always correspond with the speed of the delivery of the tubing or other fabric from the die in its plastic state, so that the said fabric may be delivered without be iug stretched, as it wouldbe if the apron were too fast, and without being caused to become serpentine or wrinkled,asit would if the apron were too slow.

It also consists in certain details of construction hereinafter described and claimed.

We will now proceed to describe the invention in detail in its application to a machine for making tubing, and afterward to briefly describe some modificationsiwhich are necessary to adapt it to other purposes.

screw, the-die, and the core as constructed for covering wire. 'Figs.1,3,-9, 10,11 are on 'a similar scale. The other figures are on a slightly larger scale.

Similar letters of reference indicate corresponding parts in the several figures.

B is a standard, upon the top of which-is constructed or firmly secured, the trunk A A, which consistsof a truly-bored horizontal cyl- 1o inder, A, surrounded bya'jacket, A': To one end of this trunk is bolted the. annular head D, in which is secured the nozzle if, or, as it may be termed, the die for giving form to the exterior of the tubing made by the machine, and which contains the core I), for giv-, ing form to the interior of the said tubing, and also contains the adjustable bridge b, which holds the said core.

In the cylinder A is placed the presscr,

which, as shown in Fig. 2, consists of a screw;

a, having a solid center, and having the center circumference of its thread fitting. snugly to the bore of said cylinder, a portion of the stock of the said screw being left plain, as 23 shown at a, to close the end of the cylinder A farthest from the head D. A feed-opening, E, is provided in the top of the cylinder near that end.

To the end of the stock of the screw a which projects beyond that end of the cylinder last mentioned, is firmly secured a worm-wheel, 0, through which the screw iscapable of receiving aslow rotary motion from an endless screw, To 'the same end of the cylinder is-secured by strong bolts or rods f, one on each side, a

.yoke or fixed cross-head, f, into the center of which is screwed the'ad'ustablebearing-screw e, which is exactly in ine with the pressure-- 0 screw a, and .wh1 ch serves as an abutment for the pressure-screw, to sustain the latter in its operation of forcing-the material through the cylinder and thedie byits rotary motion with in the cylinder. The opposite end 'of the .1, 5 pressure-screw a is about flush with the corresponding end of the cylinder A, and as close as practicable to the core-bridge b, the thread being continued to the said end, and the spiral cavity of the thread being open to thesaid end. 0 A jain nut, e", is applied on the bearing-screw e, at the back of the yoke f, for the purpose of securing the said screw against turning when properly adj usted' in relation to the trunk or cylinder and the core-bridge and die. --Be-- tween the inner end of the abutment-screw e and the corresponding end of the pressurescrew 01, there is a broad-headed thrust-pin,-

which is fitted t0 the yoke f and prevented from turning therein by a feather, e, the said:

pin' receiving and transmitting to the said screw 6 the thrust of the pressure-screw when the latter is in operation.

The adjustable core-bridge b, before mentioned, is in the form of a-flat circular disk 6 having a solid center, which is drilled and tapped for the reception of the core b, and into which the core is screwed firmly, and

around this solid center are openings, as shown in Figs. -2 and 5, for the passage through it of the material of which the pipe is to be formed. This bridge is received in'a circular cavity, of larger circumference than its own exterior,

provided in the inner face of the head D, which abuts against the end of the trunk A A, and the said bridge is fitted snugly but movably,

as by a ground joint, between the face of said cavity andvthe end'of the cylinder A, so that it maybe adjusted bymeans of radially-arranged adjusting -scre\ vs h h h", screwing through the sides of the head D, for the purpose of adjusting it and the core to bring the latter perfectly concentric with the die bflwhich is screwed into the central opening provided in the head D. This central opening and the adjacent back part of the interior of the die are tapered, as shown in Fig. 2, to render easy the passage of the plastic material from the pressure-cylinder to the die, the outer portion of which, in which the exterior of the'tubiug is formed, isbored cylindrically. The die be ing screwed 'into the head is easily removable to provide for the use of dies of differentsizes,

according to theexternal size of the tubing to be madegand the core being screwed into the core-bridge can also be removed and an- .other of different size substituted.

divided longitudinally by a central partition, as shown in the inverted plan, Fig. 4, into. twocompartments, one of which is always kept supplied with .steam by a pipe, 1', and

the other with cool water by a pipe, 2', for the purpose of supplying either steam or water tothe interior of the jacket Aof the pressure IIO cylinder, or to the annular jacket formed in v the head D, or to both of the said jackets, as

may be desired.

To provide for the distribution of the steamy and water, there are fittedinto the partition in the steam and water chest 0, two valves or cocks, H, the former, ,l, to form communication between either compartment of the chest andjthe' jacket of the cylinder, and the latter,

I l, to form communication between either c0mpartment of the said chest and the jacket in the head-D. These cocksor valves may be of any suitable kind. Those represented are cocks having hollow plugs whichare closed at the top but open at the bottom. In each hollow p'lug there is a single lateral opening, as shown in Fig. 2, and'in the plugseat of each there are two opposite openings, i i or. if'and '6 as shown in Fig. 4, ranging with the lateral opening in its plug and communicating one with the steam-compartment and theother with the water-compartment of the chest jacket.

0. Under the cavity of the plug 1 there is a downward passage, 1%, (see Fig. 2,) directly into the jacket A, and under the cavity of the plug of Z is a. downward passage, W branching ofi' horizontally through the end ofthe jacket, where it communicates with an opening, m, (see Figs. 2 and 3,) provided in the jacket portion of the head D, By turning the eockl by its handle 1, to bring the lateral Opening of its plug into communication with the opening I? or i either steam or water, as

the case may be, will be admitted through the said plug and passage V to the cylinder- In like manner, by turning the cock Z byits handle Z, to bring the lateral opening of its plug into communication with the opening '5 or i either steam or water will be admitted through and m to the jacket of the head. In this way the jacket, with its contents, and the head, with its contents, including the die and core, may beseparately tempered to that degree which is found best for the working of the plastic material of which the tubing is being made, and which is delivered in the required tubular form from the die b", through which it is forced by the pressure screw.

At the bottom of the trunk A, near the head 1), is an escape-pipe, k, (see Figs. 1 and 11,) for the escape of the cooling-water and the water of condensation from the jacket of the cylinder, and near'the pipe is is another pipe for the escape of the eoolingwater and water of condensation from the jacket of the head D. In order to provide for the removal of the head D without disturbing its escapepipe connection, the said pipe is attached to;

the trunk, as shown in Fig. 2, and a passage, m, is drilled into thejacket of the head from the inner face, and a corresponding passage from the end of the cylinder, to communicate with the said pipe, as illustrated at m in Figs. 2, 3, and 11. In like manner the removal of the head 1), without disturbing any other connection with the chest C, is provided for by the passages in and m i, hereinabove described. L

The main shaft (1 of the machine, which works in a long bearing secured to the standard B, is arranged transversely to the axis of the pressurescrew a. It is provided with fast and loose pulleys F F, and besides being furnished with the endless screw (2, hereinbefore mentioned, gearing with the worm-wheel c on the said screw a, they said shaft is furnished with another endless screw, it, (see Figs, 6 and 9,) for the purpose of giving motion to the delivery-apron o", as will be hereinafter described.

The said delivery-apron e, which is horizontally arranged in front of the trunk and the die I), has that part of its upper surface next the trunk as much lower than the axis of the die as the semi-diameter of the exterior of the tubing to be formed. In order to provide for the adjustment of said apron to the proper height according to the varying sizes of the tubing, and also to permit the lowering out the core-bridge and change the core, or

for any other purpose, the shaft '0' of the drum" '1) which supports that part of the apron, and which receives the motion for driving the said apron, is supported in a bearingbox, a 7 7 on the end of. a long adjustable bracket, a. (Shown in Figs. 6 and 7 This bracket u is made with a-hub, a which fits the cylindrt cal exterior of a projection, a, on a box, t, (see Figs. 7 and 9,) which contains the bear- 8o ings for a shaft, which carries a pulley, i

for driving the delivery-apron v by a band,

i (shown in Fig. 6,) running on the said pn-lley and on a pulley, e, on the shaft 12 of the apron-drum o. (See Figs. 6, 7, and 9.) This box 2%, which extends nearly through the standard B, is provided with a flange, t, (see Fig. 7 through which it is bolted to the exterior of the said standard.

To provide for adjusting and securing the bracket '10 and dropping it down to remove the apron out of the way without disturbing the band it" or disarraugingthe driving mechanism, the hub a of the bracket is constructed to serve as a clamp by being slit in adirection parallel with its axis, and having on opposite sides of the said slit, as shown in Figs. 6 and 8, lugs which are fittedwith a screw, t, which serves the purpose ofdrawing the-said lugs toward each other, and so effecting the tighttoo ening of the said clamp upon the projection a on the stationary box t, and thereby securingithe bracket in any position in which it may be placed, by turning it on the said projection and box, the said hub, when the screw [0 5 a is unscrewed, fittingthesaid projection easily enough to permit the bracket to be turned thereon by hand. The said screw it is made with a long shank, which extends beyond or to a point near the box u* on the extremity of I I0 the bracket a, where it is furnished-with a handle, a", so that the said screw can be con veniently worked by. the attendant who is adjusting the apron to the proper height.

To provide for giving to thefpulley t on the I I5 shaft 25, the necessary motion for drivingthe delivcryapron, there is secured to the said pulley and its shaft, a frietiondisk, t,-against the face of which works the periphery of a frictionwheel. rs, on a horizontal shaft, a, which is arranged transversely to the drivingshalt d and the shaft 15' in bearings n n", bolted to thestandard B, and. which is furnished with aworm-wheel, a, through which it receives from the endless screw a, hereinbefore I2 5 .mentioned, on-the driving-shaft, the motion which it imparts to the disk t and pulley ti. for driving the apron v at the slow rate of motion necessary to it. .s

In order that the speed of the apron may be {30 varied and regulated to make it agree exactly with the speed of the delivery of the tube y, from the die b", that it will not, by being too 'slow,' cause the plastic tubing to be projected its periphery nearer toor farther from the upon it in serpentine form, or by being too fast cause the tubing to be stretched, the frietion-wheel 1' s is fitted to the shaft n with a feather, o, in such manner that though it must turn with the said shaft, it may slide length-v wise thereon for the purpose of presenting center of the disk 2. For the purpose of so sliding'the said wheel on the said shaft,the hub of the said wheel is fitted, as shown in Figs. 6 and 7, with a loose sleeve,'p, which is confined longitudinally by a nut or collar, T2, but within which the said hub turns freely; and

the said sleeve is connected by a rod, g (see Fig. 6,) with the arm 9, which is fast on fulcrunrshaft g of a hand-lever, 9, (see also Fig. 1,) by the movement of which the frictionwheel is moved on its shaft. To secure the adjustment of the said whee there is secured to the standard B, a stationary slotted sectorplate, g',' to'lwhich the hand lever 9 may be secured in its adjusted position bya elamping screw, 9 This clamping-screw will, how ever, generally be left loose, and the attendant, holding the lever g in his haud,will watch the delivery of the tubing on the apron and move the lever as may be necessary to increase or diminish the speed of the apron relatively to the speed of the driving-shaft, and pressure according to the speed of delivery, which will vary considerably according to thesize of the tube produced, and will also vary in some degree with the very slight variations which are unavoidable in the speed of delivery from the die.

The friction-wheel 1- 8 may have its peripherical surface constructed in any suitable man- It is represented as having the said surface composed of the edges of a series of disks,

I ,part of the apron.

cured at any suitable height.

8, of india-rubbcr or other suitable material clamped together. In order to insure a proper degree of friction between the said wheel and the face of the disk t, an adjusting-screw is screwed into the back end of the box t, as

shown in Fig. 7, for the purpose of pressingv against the rear end of the shaft t, and a jamnutis applied to the said screw outside of the said box.

The method of supporting and adjusting the outermost part of the apron v, or that part thereof farthest from the trunk A A, and of collecting the tubing fronisaid apron, is illustrated in Fig. 10, and will now be described.

,G is a movable standard having a broad base, and heavy enough to stand in any position in which it may be placed on. a floor. To this standard a cross-head or rigid arm, w is adjustably secured by a screw-clamp, w, which permits the said cross-head to be se- To one end of -tlhesaid cross-head is attached a bracket, 10, which contains or carries the bearing for the shaft of the drum '0, whiehsupports the outer On the top of the said standard is placed a circular pan, H,whieli is so concentrically fitted to the said standard as to be capable of turning freely thereon, the

said pan being so placed relatively to the said apron as to be capable of receiving thetubing from the said apron, and to enable the tubing so received to be coiled upwithin it by the rotation of the said pan, which may be produced by the hand of an attendant,who stands by with a brush with which he dusts upon the exterior of the tubing, soapstone-powder or other material, for the prevention of the sticki'ng together of the coils of the tubing. The

bracket 20 is adjustable on or by the pin w,

which connects it with the cross-head 'w in such manner as to provide for setting the drum 1; as close as possible to the pan without touching it. This adjustment is desirable,

as the pans for diifereutsizes of tubing will be of different sizes. The crosshead w is adj ustahle in the direction of its lengtl1,or horizontally, by the clamp w for the same purpose.

In the modification shown in Fig. 12,to adapt the machine to the covering of wire, the pressure-screw a, instead of being solid, has a central bore large enough to allow the wire to be covered to pass through it, and the core b is also bored centrally to allow the wire to pass through it, the said core being tapered to its extremity,whieh terminates at the entrance to the cylindrical portion of the die.

Aunaehinc for making cord needs not to differ in any other respect from that for making tubing, except that no core is required in the former.

We are aware of Letters Patent No. 37,112, granted to ,T. Sault, December 9, 1862, and of other Letters Patent showing and describing a jacketed pressure-cylinder having at the end an outlet nozzle or die, and containing a screw which by its rotation cxpels the plastic material from the said die. \Ve do not desire to cover, broadly. such a machine as of our invention.

We are not aware that any machines heretofore made for the purpose have had a core arranged in the die and supported at its inner end by a eore-bridge which is adjustable trans- .versely to the axis of the cylinder in order to preserve the concentric position of'the core and die. We are aware that the machines heretofore used have had provision for supplying steam or cold water to the jacket of the cylinder; but we believe it to be newto. also pro- ,vide the head of the cylinder with a jacket which may also be supplied with steam or cooling water at will,;and independently of whether the cylinder-jacket is supplied wit-h steam or cool water. The construction of the cylinder with a chest having a partition dividing it into compartmentsfor stealnrand cooling-water,-and with valves and passages whereby steam or water may be supplied at 'will to the jackets surrounding the cylinder and its head, is very advantageous in using themachine for different materials and for different purposes. None of the machines heretofore used for the purpose has hadeombined'with it a delivery-apron onto which the cord, tube, I

ing tubing or cord or covering wire, of a presssubstantially as herein described.

, taining a die, of the core arranged within the or wire is delivered from the die, and mech-' anism for varying the speed of the apron to correspond to the speed at which the continuous cord, tube, or wire issues from the die.
